IMPROVEMENT. IN THE-MANUFACTURE-0FVAPOR-GAS.

Specification forming part of Letters Patent No. 92,105, dated Ju'ne29, 15159; ante dated April 10, 1869.

To all whom it may concern:

Be it knowntha't I, OHARLES A. SEELY, of the city, county, and State of New York, have invented an Improvement Relating to the Va por-Gas for which Letters Patent were issued to-me November 17, 1868; and I do herebydeclarc that the following is a full and-exact description'thereot', reference being bad to the accompanying drawing and thele'tters of reference marked thereon.

The nature of 'my invention consists in the mixing of atmospheric air with my vapor-gas and in the devices for eflecting the mixture." 7 To enableothers skilled in the art to make and use my invention, I will proceed to describe it'minutely.

The vapor-gas as described in my patent of November 17, 1868, on account of its richness in carbon, requires to be burned. from special burners provided with chimneys, in order to prevent its smoking. Moreover, certain precautions described in the saidpatent are necessary to prevent the-condensation of the va-- por-gas in the conductingpipes. ,The utility of the vapor-gas is, therefore, by reason of these facts, somewhat. circumscribed; and it is theobject of my present invention to remove the used for lighting.

One of the devices which -I employ for mix-- ing air-with the vapor-gas is illustrated in the sectional drawing hereto. attached.

A is a supply-pipe of vapor-gas, tapering toward the right and terminating in a fine jet within the funnel-shaped extremity of the exitpipe 0. k

B is a pipefortheadmission of air, furnished with a closely-fitting valve opening upward.

E isa valve having its seat at F-iand opening upward.

The operation of this apparatus is as follows: The vapor-gas, issuing with great force out of the jet A into the funnel of the pipe 0, draws with it the surrounding air, andapartialvacuum is formed in the chamber surrounding the jet-pipe. To supply this vacuum, the valve 1) I is raised and fresh air enters through the pipe 13'. Thusit will be seen that the vapor-gas will constantly carry with it air. The proportion of air thus mixed with the gas may be in good degree controlled by a register or stopcock, to be attached to the outward extremity of theal -supply pipe B. If the supply of vapor gas mixed with air he more rapid than its consumption atthe burners, the pressure in the mixer or injector, as alsoin theconductingpipes,.will increase till it might approach in amount-that of the-vapor-gas in the generator itself. To prevent such'a state of'thing's and 'to maintain the pressure of the mixed vaporgas and air within. constantjimits, I'make use of the valve EL Thisvalve is to be adjusted by its weight orbya spring, so thatit will lift at the desired limit. of pressure of the gas. Immediately above and incon tact or very near the stein of the valve E, I disposean arm of alever so that the lever shall be moved when the valve is lifted. Theother arm of this lever is brought in connection with the stopcock orvalve, which controls the flow of vapor-gas from the generatorinto the jet-pipe A. The adjustment of the valve E with the lever and stop-cock is such that the lifting of the valve E determines the closing orthe partial closing of the stop-cock and the flow of vaporgas into the injector.

I have represented the mixer in a very simple and compact form, in order that the character and purpose of my invention might be more clearly and more easily comprehended.

In practice, however, it is not in all respects in theform that will be suitedto general use. The modifications of it which are sometimes desirable I will proceed to point out.

. In place of thevalve E, a'movable crflexi- 'ble diaphragm may be substituted, the rising and falling of which by variation of the pressure of the gas serving as the motive force for operating the inlet cock or valve'of the vaporgas. Thediaphragrn may also assume the form of a bellows" of considerable capacity, so that the motive force shall'he very-ample; or the bellows may assume the form of a gasometer, in which the liquid used may be water or mercury. Now, it will readily be observed that these'devices are all modifications of what are known and are in pretty extensive use as gasdrives-air into the vapocgas.

regulators ;1' a nd I desire it to be distinctly understoodthat I make use of any of the ordinary gas regnlator devices with such simple modifications as the nature of my vapor-gas requires. I have found that gas-fitters generally have the knowledge and skill necessary foconstruct'a good working apparatus with less instruction than here given. I need here,

only. remark further that it'isnot necessary to have the-gas-regulator device-attached to the chamber of tbe jet-pipe, and, indeed, it is preferable to locate it beyond the chamber and on the ipe (J.

.T e object of the valve D is mainly to preveiit the escape of gasin case of back-pressure, and the valve is represented asbein g operated by its own weight and the pressure on either side ofit. Instead of so operating the valve,

' t'heinovement'of the gas-regulator may be connected with the valve so'that the valve shall be operated solely bysuch movement, the valve being closed-only in case of back-pressure.

Instead of the injectori'or mixing air withthe vapor-gas I have sometimes forced i'n the-air by contrivances which I consider equivalent to ,a pump, the pum p being operated by the elastic force of the vapor-gas.

As examples of this method of mixin g1 mention afew simple forms of construction The vapor-gas passes through a. meter, which meter is connected with and opcrates a second meter, which second meter The vapor-gas passes into a gasometer, which gasometer, by its rising, operates-a second gasometer containin-gair, The rising of the first gasometer is above described in con nccti on withthejnjector are to be-used.v V

" What I claim as my invention, and desire to secure byLetters Patent, is-

1. The mixing of air with my vapor-gas,'in

the manner and for the purposes described.

2. The automatic adjustment or regulation of the flow of vapor-gas andair and mixtures of them, inthemanner and for the purposes described.

i 3. The combination ot'the mixingdevices with the" generator of the. vapor-gas, in the manner described.

4. The combination .ofthe regulating deit vices with the generator and the mixing appa -rat-us,-a's described. l

' '5. The combination ofjjthe regulatingdcvices with the generatorwhen the mixer is not employed.
